Enable 1500000 baudrate

To enable 1500000 baudrate, you need to replace the kermit binary. See Khadas Kermit to download, and execute the following commands:

$ chmod +x kermit$ sudo cp kermit /usr/bin/kermit

If you want to use the 1500000 baudrate, you need to modify the ~/.kermrc speed to 1500000.
